In some levels, the Moss Capsule appears as a goal element alongside Moss.
To destroy a Moss Capsule, make activate power-ups nearby twice. Matches don't affect it. Once destroyed, the capsule releases Moss onto the field.
Moss itself is also a goal element. It takes just one match or one booster activation to collect the Moss in one cell. Each cleared cell will then get counted towards the other level goal.
